Cooling System

4. Install a rubber hose on the drain bolt in the back of the engine
block. Loosen the drain bolt. 5. Remove the reserve tank from its
holder by pulling it straight up.Drain the coolant, then put the
tank back in its holder.
6. When the coolant stops draining,
tighten the drain plug at the
bottom of the radiator.
7. Tighten the drain bolt at the rear of the engine cylinder block

securely.

Tightening torque: 7 lbf .
ft (10 N .
m,1.0 kgf.m)
8. Mix the recommended antifreeze with an equal amount of purifiedor distilled water in a clean
container. The cooling system
capacity is: 1.74 US gal (6.6 ,1.45 Imp gal)

mark. Install the reserve tank cap.
11.Install the radiator cap, and tighten it to the first stop.
12.Start the engine and let it run until the radiator cooling fan comes onat least twice. Then stop the

engine.

13. Remove the radiator cap. Fill the radiator with coolant up to the

Air Conditioning System

Your vehicle's air conditioning is a sealed system. Any major mainte-
nance, such as recharging, should be
done by a qualified mechanic. You
can do a couple of things to makesure the air conditioning works
efficiently.
Periodically check the engine's
radiator and air conditioning condenser for leaves, insects, and
dirt stuck to the front surface. These
block the air flow and reduce cooling efficiency. Use a light spray from a
hose or a soft brush to remove them.
The condenser and radiator fins bend
easily. Only use a low-pressure spray
or soft-bristle brush to clean them. AIR CONDITIONING
CONDENSER
Run the air conditioning at least once a week during the cold weather
months. Run it for at least ten minutes while you are driving at asteady speed with the engine at
normal operating temperature. This circulates the lubricating oil con-
tained in the refrigerant. If the air conditioning does not get as
cold as before, have your dealer
check the system. Recharge the
system with Refrigerant HFC-134a (R-134a). (See Specifications on page 316.)

Whenever you have the air conditioning

system serviced, make sure the service

facility uses a refrigerant recycling
system. This system captures the
refrigerant for reuse. Releasing

refrigerant into the atmosphere can

damage the environment.

Air Conditioning Filter, Drive Belts
Air Conditioning Filter
The air conditioning filter removes pollen and dust that is brought in
from the outside through the heating and cooling system/climate control

system.

This filter should be replaced every 30,000 miles (48,000 km) under
normal conditions. It should be
replaced every 15,000 miles (24,000
km) if you drive primarily in urbanareas that have high concentrationsof soot in the air from industry and
diesel-powered vehicles. Replace it
more often if air flow from the
heating and cooling system/climate control system becomes less than
usual. Have the air conditioning filter
replaced by your Honda dealer.
Drive Belts

POWER STEERING BELT
Check the condition of the two drive
belts (power steering belt and alternator belt). Examine the edges
of each belt for cracks or fraying.
Check the tension of the power
steering belt by pushing on it with
your thumb midway between the pulleys.
The belt should have the following
"play" or deflection.
Power steering belt: 0.51 — 0.65 in (13.0 — 16.5 mm)

If you see signs of wear or looseness,
have your dealer adjust or replace
the belts.

If Your Engine Overheats

The pointer of your vehicle's
temperature gauge should stay in

the midrange under most conditions.
It may go higher if you are driving up
a long steep hill on a very hot day. If
it climbs to the red mark, you should

determine the reason.

Driving with the temperature gauge
pointer at the red mark can cause serious damage to your engine.
Your vehicle can overheat for several

reasons, such as lack of coolant or a

mechanical problem. The only

indication may be the temperature
gauge climbing to or above the red
mark. Or you may see steam or
spray coming from under the hood.

In either case, you should take

immediate action.
1. Safely pull to the side of the road.
Put the transmission in Neutral or
Park and set the parking brake.
Turn off the heating and cooling/ climate control system and all
other accessories. Turn on the
hazard warning indicators.
2. If you see steam and/or spray coining from under the hood, turnoff the engine.
3. If you do not see steam or spray, leave the engine running and
watch the temperature gauge. If the high heat is due to overloading (climbing a long, steep hill on a
hot day with the A/C running, for example), the engine should start
to cool down almost immediately.
If it does, wait until the tempera-
ture gauge comes down to the mid-
point then continue driving.

NOTICE

Steam and spray from an

overheated engine can
seriously scald you.

Do not open the hood if steam

is coming out.ProCarManuals.comMain Menu Table of Contents s t

If Your Engine Overheats

4. If the temperature gauge stays at
the red mark, turn off the engine.
5. Wait until you see no more signs of steam or spray, then open the

hood.

6. Look for any obvious coolant leaks, such as a split radiator hose.
Everything is still extremely hot, so use caution. If you find a leak, it
must be repaired before you
continue driving (see Emergency
Towing on page 311).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page187). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks.
8. If there was no coolant in the reserve tank, you may also have to
add coolant to the radiator. Let the
engine cool down until the pointer reaches the middle of the tempera-
ture gauge, or lower, before check-
ing the radiator.
9. Using gloves or a large heavy cloth, turn the radiator cap
counterclockwise, without pushing
down, to the first stop. This
releases any remaining pressure in
the cooling system. After the
pressure releases, push down on
the cap and turn it until it comes off. 10.Start the engine and set the
temperature control dial tomaximum (climate control to
FULL AUTO at 90°F/32°C). Add
coolant to the radiator up to the
base of the filler neck. If you do not have the proper coolant
mixture available, you can add
plain water. Remember to have
the cooling system drained and refilled with the proper mixture assoon as you can.
11.Put the radiator cap back on tightly. Run the engine and watch
the temperature gauge. If it goes
back to the red mark, the engineneeds repair. (See Emergency
Towing on page 311.)
12.If the temperature stays normal, check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the MAX mark. Put the cap back on

tightly.

Taking Care of the Unexpected
Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and radiator cool down before
removing the radiator cap.ProCarManuals.comMain Menu Table of Contents s t
